About Clean Air Task Force

At CATF, we build momentum for solutions based on scientific evidence, intellectual integrity, and pragmatism. We know that the problem is too complex and the stakes are too high for us to limit the tools at our disposal. We challenge conventional wisdoms and explore every opportunity that offers promise, and we’ve done so for 30 years.
